如何在iPhone上的网络服务器上传一个mp3文件达到5 MB大小

Question

我想从我的iPhone应用程序上传一个音频文件到网络服务器，但是当我将它转换成NSData的时候，它将花费30到40分钟的时间进行转换，所以你能为它提供更好的解决方案吗？

Answer 1

1）。为了音频文件转换为NSData的：

NSString *audioFilePath = @""; // local path where audio stored 
NSData *audioData = [[NSData alloc] initWithContentsOfFile:audioFilePath]; 

2）。为了上传音频文件：

NSString *audioName = @"myAudio.caf"; 
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:@"http://someurl.aspx"]];  
[request addData:audioData withFileName:audioName andContentType:@"audio/caf" forKey:@"audioFile"]; 
[request setDelegate:self]; 
[request setTimeOutSeconds:500]; 
[request setDidFinishSelector:@selector(uploadRequestFinished:)]; 
[request setDidFailSelector:@selector(uploadRequestFailed:)]; 
[request startAsynchronous]; 

- (void)uploadRequestFinished:(ASIHTTPRequest *)request 
{ 
    UIApplication* app = [UIApplication sharedApplication]; 
    app.networkActivityIndicatorVisible = NO; 
    NSData *webData = [[NSData alloc] initWithData:[request responseData]]; 
    NSString *strEr = [[NSString alloc] initWithData:webData encoding:NSUTF8StringEncoding]; 
} 

- (void) uploadRequestFailed:(ASIHTTPRequest *)request 
{ 
    NSLog(@"responseStatusCode %i",[request responseStatusCode]); 
    NSLog(@"responseString %@",[request responseString]); 
    NSError *error = [request error]; 
    UIApplication* app = [UIApplication sharedApplication]; 
    app.networkActivityIndicatorVisible = NO; 
}
